LVO Flashcards
What is a Fail Passive Automatic Landing System?
In the event of a component or system failure, autopilot will disengage leaving aircraft in trim, no deviation in flight path or attitude
When will LVPs be in force?
Cloud base below 200ft and RVR is less than 800m
When runway centreline lights alternate red/white how far from end of runway?
900m
For type of altimeter minima bugs are set for CATI/II/III Approach?
Cat I - Baro / CATII/III - Rad
For LVTO with an RVR of 125m what is the max spacing of centre line lights?
15m
In the absence of a TDZ RVR how many centre line lights must be visible from the flight deck?
10
When calculating landing distance for an autoland, what is the min correction that should be made to the unfactored landing distance?
+125m for NON Winglet
+140m for Winglet
Should the RVR fall below minima after passing 1000ft, can approache be continued
Yes - To DA/DH
How is a CATII approach defined?
Precision approach, DH less than 200ft but more than 100ft, an minmum RVR of 300m or more
What is a Fail Operational Automatic Landing System?
In the event of a component or system failure, the aircraft can continue with a fully automatic landing in Fail Passive mode
How is a LVTO defined?
RVR less than 400m
Min RVR for LVTO?
125m
What is the ILS sensitive area?
Area beyond Critical Area where movement of aircraft and vehicles is controlled to prevent interference with the ILS signals during LVPs
How would you know you’re clear of the ILS sensitive area after landing
Entire aircraft has passed beyond point where taxiway centre line lights change from yellow/green to green
Assuming no emergency, how many approaches during LVOs?
Two max
Should the runway RVR fall below minima with the aircraft above 1,000ft above aerodrome, what actions required?
Should be discontinued at 1000ft (approach ban)
What is the minima for a CATI approach
200ft cloud base / 550m RVR
What is the minima (company) for a CATIIIA Approach
50ft / 200m RVR
